We are working on adding one more. The idea that each number means a quantity and that the quantity goes up by 1 at each new number, is a powerful concept and is easily taken for granted. By visualizing 1 more, students can see the power behind their numbers.
Using SumBlox, we can see that numbers grow and that each number has a bigger quantity.
Partner game where one person puts down a number card the other person puts down a card that is 1 more.
